Mitral valve repair versus replacement for degenerative mitral regurgitation in patients with poor ejection fraction: A 20-year propensity-score matched analysis of early postoperative outcomes.
ObjectivesTo compare early postoperative outcomes between mitral valve repair (MVr) and replacement (MVR) in patients with degenerative mitral valve disease (DMVD) and poor preoperative left ventricular ejection fraction (LVEF).MethodsA retrospective propensity-score matched analysis of 1,138 patients (612 MVr, 526 MVR...
